Laser power density, also known as irradiance, refers to the amount of laser energy delivered per unit area, typically measured in watts per square centimeter (W/cm²). It is a critical parameter in determining the interaction of laser light with materials, affecting processes such as cutting, welding, and medical treatments.

Cutting refers to the process of removing material from a larger piece to achieve a desired shape or size, utilizing tools or techniques that separate the material along defined lines. It is an essential technique in various fields such as manufacturing, construction, and crafts, and involves understanding material properties and tool selection to achieve precision and efficiency.

Medical treatments encompass a wide range of interventions aimed at diagnosing, alleviating, or curing diseases and medical conditions, tailored to individual patient needs and based on evidence-based practices. They include pharmaceutical drugs, surgical procedures, physical therapies, and lifestyle modifications, often requiring coordinated care from multidisciplinary teams to ensure optimal outcomes.
